论文摘要
很长一段时间以来,电力系统状态估计(PSSE)一直是电力工程师感兴趣的研究领域。由于可再生能源的间歇性性质比以前更多地应用于电力网络,因此国家估计的重要性也增加了。由于新网络的复杂性和电力网络规模不断增长,因此在实时分析系统或可靠性问题时面临诸如通信瓶颈等问题。分布式状态估计是解决上述问题的解决方案。为其引入了不同的实现方法。本文的结果是双重的。首先,我们根据大多数重要因素,例如迭代编号,收敛速率,需要传输到每个区域的数据等最重要的因素,研究了分布式PSSE(DPSSE)问题的不同方法。接下来,我们提出并讨论了针对方法和上述因素的新分布式停止标准。最后,完成了所有应用方法的总效率之间的比较。
Power System State Estimation (PSSE) has been a research area of interest for power engineers for a long period of time. Due to the intermittent nature of renewable energy sources, which are applied in the power network more than before, the importance of state estimation has been increased as well. Centralized state estimation due to the complexity of new networks and growing size of power network will face problems such as communication bottleneck in real-time analyzing of the system or reliability issues. Distributed state estimation is a solution for the mentioned issues. There are different implementation methods introduced for it. The results of the paper are twofold. First, we examined different approaches to distributed PSSE (DPSSE) problem, according to most important factors like iteration number, convergence rate, data needed to be transferred to/from each area and so on. Next, we proposed and discussed a new distributed stopping criterion for the methods and above-mentioned factors are obtained as well. Finally, a comparison between the total efficiency of all applied methods is done.
